Same here.  For the last two days.  I have my activation key, but can’t even find where to place it.

menu/help/license

This is a situation in which Google or another search engine is also definitely one’s friend. I just entered the text " how do you activate em client" into the search field and a FAQ page (containing the answer) on the eM Client web site was the first search result.

(The search utility within eM Client’s online help isn’t of much use in this case.)
